ALCOHOL BLOWPlPE-LANI P.

SPECIFICATION forming part of Letters Patent No. 560,748, dated May 26, 1896..

Application led May l1, 1894. Serial No. 510,853. (No model.)

To all whom, t may concern.-

Be it known that I, ROBERT SINGLETON PEABODY, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Alcohol Blowpipe- Lamps, of which the following is a specification.

One object of my invention is to provide efficient and convenient means for interrupting or completing a supply of alcohol or other inflammable material to the lamp wick, whereby the lamp may be held in inclined or partially-inverted position for use with a blowpipe without danger of the escape of iiuid through the wick-tube.

Anothei1 object of my invention is to protect a cotton or analogous wick from burning and forming charred projections that would, if present, interfere with the advantageous use of a blowpipe.

My invention consists of the improvements hereinafter fully described, and particularly referred to in the claims.

Referring to the drawings, Figure l illustrates, partly in section and partly in elevation, a lamp embodying features of my invention; and Fig 2 is a transverse sectional view of my improved wick.

Referring to the drawings, l is a base provided with a reservoir 2 and a supply-chamber 3, communicating with each other through a pipe 4.

5 is a wick-tube screwed into the top wall of the supply-chamber 3, and provided with a milled head G, by means of which it may be rotated.

7 is a plug mounted in the chamber 3 and adapted to penetrate and close the lower end of the wick-tube when the latter is screwed down and to clear. the lower end of the wicktube when the latter is screwed up.

8 is a vent-an d-stopper screw inserted into one of the walls of the reservoir 2 and adapted when screwed down to preclude the admission of airthereto, whereby fluid is prevented from entering the chamber 3, and to permit of the entrance of air when screwed up,

5o whereby fluid is permitted to flow freely into IO from burning, whereby the formation of charred projecting pieces, such as would interfere with the use of a blowpipe, is avoided, while at the same time the wicking I0 insures an ample supply of alcohol or other inflammable material to the flame.

The mode of operation of the hereinabovedescribed lamp is as follows: Whenever it is necessary or desirable to hold the lamp in inclined position for use in connection with a blowpipe, the supply of iuid to the wick may be accurately controlled and, if necessary, wholly checked by the simple operation of turning the milled Ahead 6, which is in close proximity with the fingers of the operator. If asmall quantity of the fluid should accidentally escape from the wick-tube, it will, when the lamp is turned upright, collect in the cup Il without reaching the hands of the operator. Moreover, the supply of fluid may also be controlled and,.if necessary, checked by means of the screw 8, which may be adj usted before the'lamp is taken in hand for use with a blowpipe.

When the lamp is to be lighted, or as often Y as is necessary, the wick l0 is pulled up so as to project beyond the metal tube bly means of a pin or in any preferred manner, and inasmuch as the wick 10 is secured or attached to the asbestos envelop 9 it follows that the latter is also pulled up and prevents the cotton or analogous wicking 10 from burning and forming charred projections that would interfere with the use of a blowpipe, as has been already described.

Having thus described the nature and objects of my present invention, I declare that what I claim as new, anddesire to secure by Letters Patent, is

1. A blowpipe-lamp, comprising a reservoir provided with a vent-and-stopper screw, a supply-chamber communicating with the IOO reservoir and provided With a plug, and a revwith and disengagement from said plug, sub- 1o oluble Wick-tube screwed into the supplystantially as described. chamber and having its inner end adapted In testimony whereof I have hereunto for engagement With and disengagement signed my name. 5 from said plug substantially as described. l T 1 f 2.
